The United States Environmental Protection Agency’s (US EPA) commitment to improve air quality across the USA has created an increasing demand for the monitoring of specific elements in ambient particulate matter collected on filters in residential, industrial and recreational areas. X-ray fluorescence is the preferred method to analyse samples related to air monitoring due to the non-destructive nature of the technique and the superior sensitivity achievable. The Thermo Scientific™ ARL™ QUANT’X Energy Dispersive X-Ray Fluorescence (EDXRF) instrumentation is ideal for determining concentrations of multiple elements on air filters. The bench top instrument can analyse the elements sodium to americium with minimal sample preparation and can accommodate filter sizes from 25 mm to 47 mm in diameter using a sample changer or up to 220 mm if loaded manually.
